WIRE STRAIGHTENING AND BURNISHIN G ARBOR.

Application filed January 18, 1927.

My invention relates to the class of machines used for straightening wire preparatory to various manufacturing operations thereon, and an obj ect of my invention, among others, is the provision of a device of this kind in which the friction of the straightening elements on the wire shall be reduced to a minimum; and a further object of the invention is to provide a device of this class in which the straightening elements shall also act as burnishing elements and a still further object of the invention is to provide a device that shall have a maximum of efficiency in operation and that shall be exceedingly simple in construction.

One form of device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustratedin the accompanying drawings, in which- Figure 1 is a side view of my improved arbor.

Figure 2 is a similar view looking at the arbor from a point located at right angles to the point of vlew of Figure 1.

Figure 3 is an end view.

Figure 4 is a detail view, scale enlarged, of a portion of my improved arbor illustrating its construction, the top roller at the left being removed.

Figure 5 is a view in section on a plane denoted by the dotted line 5-5 of Figure 4.

Figure 6 is a detail end view of one of the plugs on enlarged scale.

Figure 7 is a detail view of one of the plugs with the end broken away in central section to show construction.

Figure 8 is a detail view illustrating the relative positions of the members of the pairs of rollers and on a plane denoted by the dotted line 8-8 of Figure 4.

Figure 9 is a detail view illustrating a little different means from that shown in Figure 4 for holding the plugs in place and for adjusting their positions axially.

Figures 10, 11, 12 and 13 are detail views illustrating different forms of the rollers.

In the accompanying drawings the numeral 15 indicates the body of my improved arbor that may be of ordinary form and construction and embodying a shaft 16 comprising a journal at one end and a shaft 17 comprising a journal at the opposite end, lthis latter shaft having a pinion18 as a means for rotating the arbor. Means for support- Serial No. 161,746.

ing the arbor are not shown herein as these )vill be readily understood by those skilled in the art.

A series of holes 19 extend through the arbor, these holes being located preferably at equal distances apart to receive plugs 20 that are disposed in pairs, one pair in each of said holes and on opposite sides of an opening 14 extending lengthwise through the bodyy and as shown in Figure 5 of the drawings. These plugs are all of similar construction and a description of one, therefore, answers for all.

Each plug has an adjusting screw 21 freely rotatable thereon but held against independent movement lengthwise thereof, said screw having a slot 22 for the reception of a screw driver as a means for adjusting the position of the plug. A notch 23 is formed in the end of each plug for the reception of rollers to be hereinafter described. These plugs, as hereinbefore stated, are located in pairs, one pair in each of the holes 19, said plugs being arranged with the notched endsy toward each other, and these-ends may be in contact.

In the form of the structure shown in Figures 4 and 5 each plug is cut away to provide a flat surface 24 to receive a holding pin 25 that is inserted through a hole -26 extending preferably in a diagonal direction through the arbor, and as shown in Figure 4 of the drawings.

In that form of the'device shown in Figure 9 adjusting screws 27 are employed for the purpose of retaining the plugs against rotation, these screws abutting with their inner ends against flattened portionsy on the plug, and said screws being located `on opposite sides of a plane passing diametrically through the plug so that the angular adjustment of the plug in the body 15 may be obtained.

A roller is rotatably mounted in each of the notches 23 so that a pair of said rollers are located in cooperating positions in each of the holes 19. These rollers may be ernbodied in different forms, but in each case therewill preferably be a groove for the reception of the wire to be straightened, and these rollers will preferably be arranged in angular positions as hereinbefore referred to and preferably the angle of disposition of each pair of rollers being opposite to the pairs on one or both sides thereof, and as best shown in Figure 4 of the drawings.

In that form of the roller shown especially in Figures 4 and 6 each roller composed of two members 28 of duplicate form and shaped to provide a groove 29 between them and in the 4roller as a Whole. Each member' is supported upon a ball bearing 30, as especially shown in Figure 7, and a spacing ball bearing 3l is located between the members of each pair ci rollers. Balls 3l are located in recesses in the contiguous faces of the `roller members, `and the balls 30 are lo- :cated in similar recesses Yformed in the outer sides of the roller members and in thecontig- Auousiends fof iball bearing plugs-'32 located in :holes extending through brandhes 33 created by the notches 23 in the ends of the plugs 20. 'These ball bea-ring .plugs are threaded to tit fthe threaded walls of the holes in which they `are located Vand they may be provided with notches to receive a screw driver .as a means for adjusting them.

It will 'be seen, as shown in 'Figure 7, that the roller membersottI each pair of rollers may have a tipping action .relative one to the other, so that they will readily #adj ust them selves "to any inequalities in the `wires being straightened. The ,plugs 32 maybe secured in place as by set screws 34.

The `structures shown in Figures l0 to 13 `are very similar to those `shown in the preceding figures and hereinbefore described, `the ldilferences being principally :in the sha-pe of the roller members, said .members in the structure of Figure 'l0 having a istn. ight f bevel and the members 36 in `Figure 13 having a iconivex sloping surface, especially adapted torcperation upon a Wire 37 of anguiar shape in cross section.

ln the structure shown in Figure l1 the roller member 38 has conical bearings 39 toreceive a pin 40 with a conical end and :a screw 4l with a conical end. A sleeve 42 is employed flier holding the pin in place. lWith this construction the pin "may be 'duplicated on the opposite side and lthe same `is true of the screw.

In that form of fthe device shown in Figure l2 the roll-er member is of a :single piece, as in Figure ll, and :it is supported iat opposite sides upon balls lll that :are lheld in 4place in recesses in branches ci the plug Q0 as -by a sleeve in a manner similar to the Vstiu'lcture shown in Figure ll.

It will be noted that the pairs of plu-gs in each of the. lholes 19 may be adii-istably positionedlaterally of the tbody 155, and it will be :found that il this adjustment of the several plue's is so made that the entire set ot plugs will assume a curved or arched toi-m with the highest point o'f the `arch at about the lengthwise centero the body, as shown in Figure 2, extremely satisfactory results will be obtained.

The construction of the Aplugs and the roller members as illustrated and described herein enables the device to be used not only as a wire straightener, but also as u'irc buruisher, it having,y been 'found that the Wire when dclivered trom the structure will be nicely burnished, and in accomplishing this result I time the rate oli rotation ol the body and the rate of travel of 'the Wire throi jh the straightener succeeding in such ratio met sets ot roller members 2t? will make contact with the wire in diiercnt helical lines from that iltraveled by precedingl sets ci roller ment bers so that substantially the entire surface of 'the Wire Will bc acted 'upon by the roller members, and so tar as appearance is concerned the entire surface of the Wire will be thus burr red.

In straighteners heretofore employed and comprising straightonine` elementsy havinggl u purely iuilfoing,` contact with the Wire, as the body rotated and as the wire Vtravels through the body, much `di'iiiculty has been encountered by reason of the great friction 'that ten( s to rotate the wire which, however, must be held against rotation and special means are therefore required to prevent such v'rotation `of the wire. This is especially truc Aat the time the end of the wire passes m the reel upon which it is Wound, which owin to the curved form `oi the uire caused by i s winding upon the reel, will havingl a vrhipping or `gyratory motion imparted te it it rotation talzes place, and even at other times this friction may cause the wire to be Itwisted 01H.

By the use of the roller starei, ning and burnishing members 'herein rllu y rated and `described this friction is reduce-l to a minimimi and to such extent that the tendency of the Wire `to rotate practically eliminated and the ordinary feed rolls will be found sul# lieient tto prevent the n'ire from rotcting and no special device will, therefore, be 'required lor this purpose.

The axis or" each of the rollers inclined in such direction that both travel ot' the wire through 'the bony and rotation of the body about the Wire is aided, and thedegrce or angle will be such as to secure theme rem. 'lhat is, the axes are so inclined that revolu tion oif the rollers around the Wire will c; use rotation of the rollers in a dirruztion-to aid in the results obtained, that. is, movement ol" wire is impeded to minimmu d" rolllers rotatingv in a `direction cause-d by such rotation.

In accordance With 'the provisi patent stat flhave de."-l `I"bedthe Y. of operation of 1y invention, togetne the device which l nou' consider to rel' the best embodiment thereof; but desire chave it understood that 'the device shown is only illustrative and that the invention new be carried out by other means and plied to uses Iother than those allieve out.
